Spec Drift — changed_response / auth_change

Exchange: baozi
Affected file: core/src/exchanges/baozi/errors.ts
Reference: Baozi Solana program IDL (current)

Finding

errors.ts maps Baozi on-chain error codes to human-readable names. At least 6 mappings are wrong against the current program IDL:

These appear to be carry-over from an earlier IDL version that was renumbered during a program upgrade.

Impact

When the Baozi Solana program returns one of these error codes (e.g., a bet below the minimum size returns 6023), the adapter looks up 6023 in errors.ts, finds a different error name (or nothing), and either surfaces the wrong error message to the user or falls through to a generic "unknown error" path.

Concretely:

• A bet that is too small shows as the wrong error (or generic) instead of BetTooLow
• A bet that is too large shows as the wrong error instead of BetTooHigh
• A frozen-betting state shows as the wrong error instead of BettingFrozen

This makes on-chain failures opaque to end users and to any retry/fallback logic that branches on error type.

What needs updating

• Audit the full errors.ts mapping against the current Baozi program IDL
• Correct all mismatched codes (at minimum the 6 listed above)
• Add a comment referencing the IDL version the mapping was taken from so future drift is detectable
